In the following room, how would you design a HT giving the following considerations:

1. The mains are of primary concern for music also
2. The primary listening volume will be around 80db, and only cranked to 90-95db maybe once a month, but never over that.
3. 65 watts per channel
4. Deep subwoofer as possible.

All of the speakers in the room currently seen are going to go. They sound like crap. I think that anything I make would sound better (although I might tinker with them and upgrade the x-o later).

Any ideas? Also, I'm on a college budget so not TOO expensive. I am not sold on a specific budget at the moment. I want a wide open sound with the surrounds like a theater, but a very musical sound with the mains, as I listen to music A LOT.
